Research & DevelopmentUniversity of Sydney researchers have developed a circular, sunlight-driven liquid gallium process that splits seawater into hydrogen at 12.9% solar-to-hydrogen efficiency, eliminating the need for purified water or grid electricity. Imagine tapping into sunlight and seawater to churn out clean hydrogen without needing a single watt from the grid. But that’s exactly what researchers at the University of Sydney have achieved in a recent study, showcasing solar-to-hydrogen efficiency at an impressive 12.9%. No more worrying about purified water demands or costly electricity inputs! Desalination plants, the need for purified water, and reliance on grid power can...
